ELASTIC WIRE CABLE.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed January 18, 1909. Serial No. 472,986.

To all whom 'it may concern:

Be it known that I, THOMAS W. OOLLERAN, of the city of Toronto, in theProvince of Ontario, Canada, have invented certain new and usefulImprovements in Elastic Wire Cables, of which the following is aspecification.

This invention relates to improvements in wire cables such as shown inmy prior Canadian Letters Patent N 0. 87,049, dated May the 10th, 1904,and my object is to devise a cable possessing greater strength and,elasticity than the cable therein shown.

In carrying out my invention I form a core by interweaving a pluralityof coiled strands to form a filled coil. About this core I form a tubeof interwoven coils, each running parallel to the axis of the cable. Thespecific weave is not important provided sufiicient space is left withinthe tube for the core. For instance, a Weave such as shown in the priorpatent above referred to might be employed.

Figure 1 is a perspective view of a portion of a cable constructed inaccordance with my invention. Fig. 2 is a perspective view of a portionof the core before the latter has been completely filled.

In the drawings like letters of reference indicate corresponding partsin the different figures.

In forming my cable I first construct a core A. This is formed byinterweaving a plurality of coiled wires in the manner shown in Fig. 2until the spaces between the coils are completely filled or closed, asshown in Fig. 1. Such a coil is of course well known in the art. Aboutthis core I form a tubular elastic cable B by interweaving coiled wiresrunning parallel to the axis of the cable. This may be formed ifdesired, in the manner described and illustrated in my prior patenthereinbefore referred to, care being taken that a sufficient width offabric be formed before being joined into a tube to provide a centralspace sufliciently large to contain the core A. Any weaves may, however,be employed in which a tube is formed by inter- Weaving parallel coiledwires. Other elastic cores might also be used though I prefer a' coreconstructed as described and illustrated.

An elastic cable constructed in accordance wlth my prior patent wasnaturally limited in slze, and accordingly in strength and elastlcity,whereas with my present arrangement a larger cable can be formedcontaining more wire, and which therefore can be made of any desiredsize, strength and elasticity merely by varying the size of the elastictube and the size of the core.

I have demonstrated that a cable constructed in accordance with myinvention forms a very strong and elastic supporting cable for use atthe edges, or elsewhere, of the woven wire fabrics commonly employed formattresses.

I am aware that wire cables with cores are already known in the art, butthey are either formed with the external part of ordinary twistedstrands passing helically around the core or else braided, in which casethe individual wires also pass helically around the core. In myconstruction no wire passes around the core but each runs in adirectionparallel to the axis of the cable and is coiled to intermesh with itsneighbors. It will be seen that the individual wires of the core alsoare parallel to one another and to the wires of the tube. This it iswhich gives the cable its great elasticity, an elasticity far in excessof that of ordinary twisted or braided cables.

What I claim as my invention is 1. An elastic wire cable comprising atube of interwoven coiled wires, the wires of said tube running parallelto the axis thereof, and a separate core of interwoven coiled wires.

2. An elastic wire cable comprising a tube of interwoven coiled wiresthe wires of said tube running parallel to the axis thereof, and aseparate core of interwoven coiled wlres formed as a close or filledcoil.

3. An elastic wire cable comprising a tube of interwoven coiled wiresthe wires of said tube running parallel to the axis thereof and aseparate elastic core.
